More Mississippian Bryozoans

I am trying to figure out what these rings are on the rock I showed yesterday. This rock has layers of Fenestella all over it.

Is it a base for the bryozoan or maybe part of a blastoid?
All I have found at the Hodgenville, Kentucky site are bryozoan remains and some fragments of brachiopods and gastropods.
